Application

Metal Borohydrides as Hydrogen Storage Materials
Sodium borohydride (NaBH4) is a stable hydrogen carrier, which can be used as a chemical hydrogen storage material. It can also be used as an anodic fuel for alternative energy applications such as the fabrication of fuel cells. It can also be used in the reduction of graphene oxide in the presence of CaCl2 as a catalyst.
Sodium borohydride has promising application as a portable hydrogen storage material.
